Abstract: A method for rotary steerable drilling, comprising calculating a first plurality of convergence plans if an estimated position of a drill bit is not within a defined margin of error of a desired point along a planned path for a borehole, calculating a second plurality of convergence plans if the estimated position of the drill bit is not within the margin of error, selecting a convergence plan that best satisfies a set of target parameters from the first and second plurality of convergence plans, producing a set of control parameters representing the selected convergence plan, transmitting one or more commands to one or more rotary steering components to actuate the one or more rotary steering components, in order to alter the planned path for the borehole in accordance with the set of control parameters, and drilling at least a portion of the borehole based on the set of control parameters.

Abstract: A method for determining geological formation characteristics involves driving a bottom hole assembly (BHA) in a borehole. At least one mechanical drilling parameter generated is detected responsive to operation of the BHA in the borehole. At least one geological formation characteristic is identified responsive to the detected at least one mechanical drilling parameter. The identified at least one geological formation characteristic is provided to a surface steerable drilling system. Operation of the surface steerable drilling system is controlled responsive to the at least one geological formation characteristic.
